Agree with the first sentence. I do now quite get what you are saying in the second sentence. If you are saying practicing something to the point of habit doesn't increase the likelihood of using it when needed, I have to disagree.The idea that having more options makes it harder to choose one is an over-generalization from a very specific piece of cognitive research. There's no evidence I know of to support it for a well-trained set of skills.
I also know of no evidence that suggests training a skill over a longer period leaves one with no better chance of being able to use it than training it 30 hours once, some time ago.
